Abbott's XIENCE V(TM) Drug Eluting Stent Outperforms TAXUS(R) in Key Efficacy and Safety Endpoints Out to Two Years

red to TAXUS (4.1 percent for XIENCE V vs. 6.8 percent for TAXUS, p-value=0.03)*.

-- Low rates of stent thrombosis between one and two years, defined as very late stent thrombosis, per Academic Research Consortium (ARC) definition of definite/probable stent thrombosis (0.5 percent for XIENCE V and 0.8 percent for TAXUS). The ARC definitions of stent thrombosis were developed to eliminate variability in the definitions across various drug eluting stent trials.

* Event rates are based on Kaplan-Meier estimates; p-values are for descriptive purposes only.

Strong Results in Complex Patients: SPIRIT III Subgroup Analyses

Also presented during TCT, a variety of subgroup analyses from the SPIRIT III trial demonstrated observational evidence of strong performance by XIENCE V in a variety of patients and lesion types that represent complex patients. The results consistently favored XIENCE V compared to TAXUS at two years across multiple subgroups examined, including patients with small vessels and multi-vessel patients. In diabetic patients, the analysis showed there were no observed differences between XIENCE V and TAXUS at two years. The SPIRIT III trial was not designed to analyze statistical differences in any of the patient subgroups, as the sample sizes were too small to draw firm conclusions.

"With the subgroup analysis, we saw encouraging trends of lower event rates between one and two years for patients treated with XIENCE V compared to patients treated with TAXUS, regardless of patient or lesion complexity," said John M. Capek, Ph.D., executive vice president, Medical Devices, Abbott. "Even though the SPIRIT III trial was not designed for statistical comparisons in subgroups, these positive trends demonstrate that XIENCE V performs in a consistent manner and gives physicians confidence in XIENCE V as they consider what is the most effective treatment for their patients."
